Definitions
- the invention relates to a steering column for a motor vehicle, comprising a casing unit, in which a steering spindle is rotatably mounted about a longitudinal axis extending in the longitudinal direction and which has at least two casings which are adjustable in the longitudinal direction by an adjustment path relative to one another, with a part designed as a transition section section of the adjustment path, the jackets are guided with greater play than in a section of the adjustment path designed as a functional section.
- a steering column for a motor vehicle has a steering shaft with a steering spindle, at de ren rear end facing the driver in the direction of travel, a steering wheel for introducing a steering command by the driver is attached.
- the steering spindle is rotatably mounted in a Mantelein unit with which it forms an actuating unit.
- the jacket unit is held by a support unit attached to the vehicle body.
- Adjustable Lenkklan allow adjustment of the steering wheel position relative to the vehicle body by adjusting the jacket unit relative to the support unit.
- the steering column adjustable in the longitudinal direction, i.e. in the axial direction of the steering spindle or in the direction of the longitudinal axis, in order to adapt the steering wheel in the operating position to the driver's position in manual ferry operation for convenient manual steering intervention.
- autonomous vehicles in autonomous ferry operation, if there is no manual steering intervention, the steering column can be pushed further together by further adjustment in the longitudinal direction from the operating position in order to bring the steering wheel into a stowed position outside of the operating position and to free up the vehicle interior for other use .
- a jacket unit with a telescopic arrangement of jackets is known from DE 102018211 041 A1, for example, for longitudinal adjustment and for stowing.
- These jackets comprise an outer jacket tube, also referred to as a lower jacket, which is supported on the body at the front in the direction of travel and into which an upper jacket constructed as an inner jacket tube is immersed in a telescopically adjustable manner in the longitudinal direction.
- a motor-driven adjustment drive is provided, which is designed as a spindle drive and engages the casing pipes in the longitudinal direction.
- a maximum adjustment can be made by means of the adjustment drive up to a driver-side end position in which the jackets are pulled apart up to a maximum of egg nem end stop.
- the maximum possible adjustment range between the stowed position and the end position defines the adjustment path of the steering column.
- the steering column is adjusted so that the steering wheel is in an individual operating position within an operating area which defines an adjustment range of ergonomically meaningful operating positions for entering steering commands.
- the operating area is provided by a defined functional section of the adjustment and is also referred to as the comfort area.
- Another functional section of the adjustment can be located in the area of the stowed position.
- the sub-area of the adjustment path which is located in the transition between the operating area and the stowed position, forms a transition section of the adjustment.
- the transition section will only run through during the transition outside the functional section, a lower stiffness is acceptable there.
- the practical implementation requires a complex processing of the jackets to form functional and transition sections with different dimensions and fits of the jacket tubes, and an individual design of the jacket tubes for use in steering columns with different lengths of control and transition areas.
- a steering column for a motor vehicle comprising a casing unit in which a steering spindle is rotatably mounted about a longitudinal axis extending in the longitudinal direction and which has at least two casings which are guided in the longitudinal direction to be adjustable relative to one another by an adjustment path, with a section formed as a transition section of the Adjustment path the jackets are guided with greater play than in a section of the adjustment path designed as a functional section
- one jacket has a guide track
- another jacket has a guide element which, guided in the longitudinal direction, engages in the guide track and thereby in the guide track has a guide play which is greater in a transition section than in a functional section.
- the guide is not generated by the jacket tubes themselves, as in the prior art, but by a guide device provided functionally independently of this on the jackets.
- a guide track elongated in the longitudinal direction can be fixed to one of the jackets, and a guide element corresponding to this guide track and cooperating in a guide engagement on another jacket.
- the interaction of the guide track and the guide element makes it possible to provide forced guidance in the longitudinal direction, which can be optimized with regard to its specific guide characteristics over the adjustment path, regardless of the other design of the sheaths.
- the guide play existing between the guide track and guide element can be enlarged in sections in order to generate a play-containing, loose form fit in a transition section, which has a low friction with respect to a relative adjustment of the shells.
- a rigid connection of the sheaths in a functional section can be created solely through a precisely fitting coordination of guide track and guide element with little play.
- the guide track and the guide element can be manufactured and adapted with less effort, for example, to provide functional and transition sections of different lengths than would be required by machining the casing pipes in the prior art. As a result, the manufacturing effort can be reduced and the flexibility of use can be increased.
- the jackets can include at least an upper jacket and a lower jacket.
- the upper coat denotes the rear with respect to the direction of travel, driver-side Man tel, and the lower coat denotes the front, vehicle-side or body-side coat in the direction of travel.
- at least one intermediate jacket preferably telescopically adjustable in the longitudinal direction, can be inserted between the two jackets, for realizing a multiple extension with a large adjustment range.
- guide tracks and guide elements can be arranged on the jackets and intermediate jackets.
- the guide track and the guide element are designed in such a way that an adjustment takes place without damage in the transition section and in the functional section, i.e. the guide track and the guide element are undamaged to one another after an adjustment, i.e. essentially no permanent deformation occurs, which the guide function noticeably influenced.
- the wear due to the sliding contact after a large number of adjustment operations is not to be understood as damage. In other words, there is no energy absorption by plastic deformation between the guide element and the guide track in order to reduce energy input due to an accident in deformation work.
- the guide track and the guide element are out of contact with one another in the transition section, that is to say they do not touch one another.
- a sliding guide with clearance can be formed.
- the jackets can comprise telescopic jacket tubes.
- a telescopic arrangement of the jacket unit comprises at least one outer jacket tube and an inner jacket tube that can be telescoped therein in the longitudinal direction, and in a multiple telescope one or more intermediate jacket tubes inserted between them.

- a guide track according to the invention and a guide element can be arranged corresponding to one another on the inside on an outer jacket and on the outside on an inner jacket immersed therein.
- the guide track and the guide element form a form fit that is effective in the circumferential direction.
- a form fit in the circumferential direction can be achieved, for example, by engagement between the guide element and the guide track in the radial direction Direction with respect to the longitudinal axis are generated. In this way, an anti-twist device can be created between the jackets.
- the guide play between the guide track and the guide element can exist in the circumferential direction.
- Such a guide play can be formed out with advantageously little effort, for example in the case of a form fit that is effective in the circumferential direction.
- a loose form fit with a relatively large guide play can be implemented through an air gap between the guide track and element, whereas in a functional area a small amount of play is specified between the guide surfaces of the guide track and element directed against each other in the circumferential direction, for example also by a low-play or Backlash-free tensioning of the guide surfaces by means of a pre-tensioning force.
- the radial play between the jackets can be kept unchanged, so that the manufacturing effort can be lower than in the prior art for the un ferent radial play required processing of the casing tubes to provide functional and transition sections.
- the guide track has an elongated guide groove into which a guide projection of the guide element engages and which has a smaller groove width in sections.
- the guide groove extends in the longitudinal direction and is open radially with respect to the longitudinal axis.
- the corresponding guide projection can, for example, be peg-shaped or web-shaped and protrude radially into the guide groove.
- the guide groove is fixed in the longitudinal direction and preferably also in the circumferential direction on the outside of an inner jacket or on the inside of an outer jacket, and the corresponding guide projection correspondingly radially opposite one another on the other jacket.
- the lateral guide play ie the guide play existing in the circumferential direction between the groove flanks of the guide groove and the guide projection
- a functional section is provided outside such a functional section.
- a transition section with greater guide play can be provided simply by a larger groove width, in which the guide projection laterally, i.e. in the circumferential direction, has an air gap to the groove flanks, so that there is a loose form fit. It is advantageous here that a guide groove with different groove widths can be produced with little effort. A reliable and precise longitudinal guidance can be guaranteed during operation.
- the guide groove can be closed at the end in order to provide a longitudinal stop for the guide projection, preferably at both ends, or only at one end.
- the guide track has an elongated guide projection which engages in a guide recess of the guide element and which has a larger web width in sections.
- the guide projection is in the longitudinal direction, it stretches, and protrudes radially with respect to the longitudinal axis, and can for example be web-like or rail-like.
- the corresponding guide recess can, for example, be groove-shaped and encompass the guide projection, i.e. the guide projection protrudes radially into the guide recess.
- the guide projection is fixed in the longitudinal direction and preferably also in the circumferential direction on the outside of an inner jacket or on the inside of an outer jacket, and the corresponding guide recess is correspondingly radially opposite on the other jacket.
- the lateral guide play that is to say the play existing in the circumferential direction between the groove flanks of the guide groove and the guide projection
- a functional section can be provided outside such a functional section.
- a transition section with greater guide play can be provided simply by having a smaller width, in which the guide projection has an air gap laterally, i.e. in the circumferential direction, to the flanks of the guide recess, so that there is a loose form fit. It is advantageous here that a guide projection with different widths can be produced with little effort. A reliable and precise longitudinal guidance during operation can be guaranteed
- a smaller guide play is formed in one end section or in both end sections of the guide track.
- the length of the guide track is dimensioned so that the guide element can be moved along the adjustment path of the jacket unit therein.
- a functional section can be formed in the end area of the guideway in that the guide element is located when the operating area of the steering column is set, that is, the jackets are pulled apart. It can also be provided that a functional section is also implemented in the other end section, which corresponds to the pushed together stowed position of the jackets, in order to enable secure and vibration-free fixing in the stowed position.
- the guide track has a guide track body and / or the guide element has a guide element body that is attached to a Sheath is attached or formed.
- the guideway body is designed to be elongated in the longitudinal direction and can, for example, comprise a profile body with a guide groove or / and a guide projection.
- the guide element body can be designed with a guide projection or a guide recess.
- an advantageous embodiment is that the guide track body and / or the guide element body is formed separately and connected to a jacket.
- the length of functional and transition sections on the guide track body and / or the guide element body can initially be specified independently of the jacket pipe arrangement. The fixation on the jackets can then take place, whereby the jacket unit can be equipped with a predetermined guide characteristic.
- One advantage is that different leadership characteristics can be achieved simply by adapting the leadership accordingly, with otherwise unchanged coats. As a result, the design, manufacturing and storage costs can be reduced, and the flexibility of the application can be increased.
- connection between the guide track and / or guide element body and a one telrohr can be made by means of fastening elements or other preferably form-fitting and / or cohesive connection methods.

- a motorized adjustment drive can be provided which is coupled to the jackets in such a way as to adjust the jackets relative to one another, at least in the longitudinal direction.
- the adjustment drive can for example comprise a spindle drive with a spindle nut arranged on a threaded spindle and an electric drive motor by which the threaded spindle and the spindle nut can be driven to rotate relative to one another.
- adjusting drives are known in principle in the prior art and are considered reliable and robust.
- the spindle nut is attached to one jacket so that it cannot be displaced in the longitudinal direction, and the threaded spindle is attached to the other jacket tube which can be telescoped for this purpose.
- the spindle nut or the threaded spindle is driven in rotation by a drive motor via a suitable gear, for example a worm or belt gear, whereby the threaded spindle or spindle nut, which is fixed relative to the rotation, is moved translationally in the direction of the spindle axis, and depending on the rela In the direction of rotation, the jackets are moved together or apart in the longitudinal direction.
- a suitable gear for example a worm or belt gear
- an energy absorption device is arranged between the guide track or the guide element and a jacket.

- the inner jacket 32 is designed as a jacket tube with a base body with a round pipe cross-section and is received for longitudinal adjustment in the outer jacket 31 and telescopically adjustable in the longitudinal direction, as indicated by the double arrow.
- a setting position which is an operating or operating position, as shown in the figures, the jacket is pulled relatively far out of the outer jacket, ie to the right in FIG. 1 and to the right in FIGS. 2 to 4 and 6 to 8.
- a motorized adjustment drive 5 is provided, which is designed as a spindle drive with a spindle nut 52 which can be driven in rotation by an electric motor 51 and is supported on the outer jacket 31 in the longitudinal direction, in which a longitudinally extending spindle nut 52 is attached to the inner jacket 32 in the longitudinal direction and non-rotatably fixed threaded spindle del 53 engages.
- a guide device 4 comprises a guide track which is formed in the longitudinal direction elongated guide groove 41.
- This guide groove 41 has a groove cross-section open ra dial towards the longitudinal axis, also referred to as a guide cross-section, and is formed in a guide track body 42 which is fixed to the outer casing 31 by means of a carrier element 43 in the longitudinal direction and in the circumferential direction with respect to the longitudinal axis L.
- a guide element in the form of a guide projection 44 is fixed in the longitudinal and circumferential directions radially with respect to the longitudinal axis L above.
- the guide projection 44 has the shape of a longitudinally elongated pin with a width G transverse to the longitudinal direction, i.e. measured in the circumferential direction.
- the guide projection 44 protrudes radially outward from a guide element body 45 and dips into the guide groove 41 from the inside in such a way that it is positively guided therein so that it can move in the longitudinal direction, i.e. is positively supported in the circumferential direction.

- a bolt-shaped expansion element 63 is pressed into this slot 62 and protrudes on the inside of the guide element body 45 facing away from the guide projection 44. Because the expansion element 63 is oversized relative to the width of the slot 62 and is pressed into the slot 62 with local deformation, the guide element body is fixed to the inner casing 32 via the profile rail in the longitudinal direction.
- the threaded spindle 53 of the adjustment drive 5 engages the inner jacket 32 via this guide element body 45 and the energy absorption device 6 for longitudinal adjustment. Only in the event of a crash, when the inner jacket 32 is pushed into the outer jacket 31 with an extremely high force peak, is the expansion element 63 plowed along with plastic expansion in the longitudinal direction through the slot 62, as indicated by the arrow in FIG Energy is absorbed.
- the carrier element 43 is omitted for better visibility, and the carrier element body 42 is schematically cut open lengthways, i.e. shown radially open from the outside, so that the view into the otherwise outwardly closed guide groove 41 is exposed.
- the guide groove 41 has a functional section A, which extends over a portion of its length, which corresponds to the operating area shown, in which the jackets 31 and 32 can be adjusted in the longitudinal direction relative to each other for setting the steering wheel position.
- the guide groove 41 has a groove width W1 transversely to the longitudinal axis L, measured in the circumferential direction.
- This groove width W1 is matched to the width G of the guide projection 44 with a small amount of guide play, so that the guide projection 44 is slidably guided in the longitudinal direction, and the guide produces a high degree of rigidity for the casing unit 3.
- the amount of the lead game results from the difference W1 - G.
- a transition section B adjoins the functional section A in the insertion direction, which is indicated by the arrow on the guide projection 44, and in which the inner jacket 32 is moved into the outer jacket 31 when moving together.
- the entire possible adjustment path essentially corresponds to the sum of sections A + B.
- the groove width W2 in this transition section B is greater than the groove width W1.
- the guide projection 44 in the transition section B preferably also has a distance from the groove bottom of the guide groove 41, and in the functional section A the guide section 44 has contact with the groove bottom of the guide groove 41, as can be seen in FIG.
- the play between the guide projection 44 and the guide groove 41 is not solely determined by the contact of the guide projection 44 on the groove flanks of the guide groove 41, but also by the contact or the existing play between the guide projection 44 and the groove bottom of the guide groove 41.
- the guide groove 41 has a groove width W3 which is smaller than the groove width W2 in the transition section B, which means that there is little play in guidance and support the stowage position is enabled.
